After playing hero in Game 3 of the ALDS on Wednesday night, Raul Ibanez is being a thorn in the Orioles’ side again today.

Thanks to an RBI single by Ibanez in the bottom of the fifth, the Yankees have jumped out to a 1-0 lead over the Orioles in Game 5.

Mark Teixeira singled to lead off to the bottom of the fifth inning for the first hit of the day off Jason Hammel. After realizing that he wasn’t being held on by Mark Reynolds at first base, Teixeira then successfully stole second base, bum calf and all. Ibanez followed with a slow roller through the middle to bring him around to score. The interesting part is that if Teixeira was held on, the Ibanez grounder likely would have resulted in a double-play.

Sabathia is looking pretty tough thus far, holding the Orioles to just one hit and a walk while striking out four. If he’s at the top of his game, one run might be enough.

You know the baseballs are different. We know the baseballs are different. Pitchers have been saying the baseballs are different. And now Major League Baseball has acknowledged that the baseballs are different in a report of findings by a team of scientists from some of the top universities in the world, like Stanford, Caltech, and M.I.T.

Though the study did not discover meaningful changes in the ball’s lift, it found that the drag coefficient of MLB balls has decreased since 2015. The researchers used a physics model to calculate that if the change in home run rate was attributable entirely to changes in drag, one would expect the drag coefficient to have decreased by approximately 0.012. The exact change in drag coefficient in the time period studied — if you’re scoring at home — was 0.0153.

It’s not the seams or the core that has changed — those aspects were tested — and it’s not the weather either. In fact, the commision couldn’t figure out what is causing the decrease in drag, despite numerous tests on all elements of the ball. It might simply come down to manufacturing advancements. Looking at you, Rawlings …

“Rawlings is always trying to improve the manufacturing process to make it more uniform,” Alan Nathan, professor emeritus of physics at the University of Illinois at Urbana-Champaign told MLB.com. “So the interesting question that comes up is whether the goal should be to improve the manufacturing process or to keep the ball performing exactly the way it is, regardless of whether it’s improved or not.”
